'In an address delivered at the Al-Aqsa Mosque on May 20, 2016, as the month of Ramadhan drew near, Palestinian preacher Sheikh Ali Abu Ahmad said that he hoped that the Caliphate would be restored in the near future and called upon the armies of the Islamic nation to rally to the battle. Abu Ahmad prayed: "Oh Allah, protect the Al-Aqsa Mosque from the filth of the Jews! Oh Allah, annihilate all the Jews! Oh Allah, enable us to kill them!" The address was posted on the Aqsa Call YouTube account.'
